What commenters say

• The new error highlighting feature in Python 3.11 will greatly improve debugging experiences.
• Removing the GIL and improving performance is crucial for Python's future growth and adoption.
• Some commenters believe that Python's ease of calling C libraries is a curse that hampers the language's evolution.
• Others argue that the lack of a JIT compiler in Python is a significant disadvantage compared to other languages like JavaScript.
• The performance difference between Python and JavaScript is largely due to the vast resources invested in JavaScript development.
• A simple JIT compiler is planned for a future Python release, which may help improve performance.
• The complexity of maintaining a JIT compiler and ensuring security should not be underestimated.
• Python's large and complex C API is a significant obstacle to evolving the interpreter without breaking third-party bindings.
